IMPROVEMENT IN APPARATUS FOR FRIZZLING CLOTH.

The Schedule referred to in these Letten Patent and making p art of the same. l

To all 'whom it may concern.-

Be it known that I, SCHAMU `MORITZ MosoHco W1trz,'of the city, county, and State of New York have invented a new and useful Instrument and An paratus for Frizzling Strips of Silk Or other Stuff; and I hereby declare that the following is afull, clear, and exact description thereof, rference being had to the accompanying drawings making a part of this specification, and the letters of reference marked thereon, in which the same letter represents the same thing in each iigure.

Figure l is, an elevation of the instrument or tool;

Figure 2 is an enlarged elevation of the acting end of the same;

Figure 3 is a diagram explanatory of the mode of using the apparatus; and

Figure 4 is a side view ofcertain Operative parts of a sewing-machine.

By frizzling, I mean converting into fringe the parts adjacent to the edgesof strips of woven goods, the instrument acting to destroy the collocation or assemblage of the threads produced by weaving, to draw out. the warp and weft threads in lines' perpendicular or nearly so to the line of the edge of the strip.

represents the reciprocating needle arm; B, the presser-foot; C, the .cloth-plate; and D, the feeding device of a sewing-machine.

Tue acting part of the instrument consists of a point or points and shoulders. I prefer two points, witha shoulder between them, the lpoints being represented at a a, and the shoulder between them at b. The points at their extremities should be sharp, and the shoulder should havea rounded edge, the points to penetrate through or between thc threads, the shouln der to bear upon the threads and draw them out.

The instrument may be brmed of an ordinary sewing-machine needle, by vbreaking it in two through the eye, and then 'by sharpening the two sides of the eye to points.

It'the part at b, between the points, be not smooth and rounded, it should be thus formed, so that the shoulder shall not cut or fray the threads, or do so as `little as possible.

'This instrument may have aV handle applied to it, and be used by hand. I prefer tomount it in the 4needle-carrier of a sewing-machine, Wheeler St Wilsons by preference, With the line connecting the points perpendicular Vto the line of fecd, but the angle of the line connecting the points to the line of feed is notessential.

In order to use the tool. thus monnted,'I need the reciprocating needle-arm, the, presser-toot, the table for supporting the goods, and the feed-bar or wheel ofav sewing-machine, and I tind that the best work is done when the feed is small or through a short distance between each stroke of the tool.

The tool should be so set as to. descend far enough `below the table to destroy the collocation of the threads to their ends.-

I nd that I can do the best work upon strips ont bias, at angle of forty-five degreesor nearly so, with the selva-ge of the goods; and in iig. 4 a strip is shown whose selvage is at c c, the `line of warp threads-being indicated at d d. I snip off one edge of this selva-ge, as at 'e e, as it is sometimes so tightly woven that it is ditlicult to frizzle. I then put the strip under the presser-foot, and set the. machine in motion, so that the tool Astrikes in at or about c. I then gradually turn the goods so that the tool strikes further and further from the' edge, and when the desired distance from the edge is reached, feed the stuff parallel with the edge,ror nearly so, the dotted line e f in the drawings indicating the track of the tool.

I prefer to commence as described, so as to make a narrow fringe at the end, as I find this enables me to frizzle without'tearing at the end ofthe stxip; and I prefer to feed the strip with the ends of the warp threads pointing somewhat in the direction of the feed, as indicated in the diagram, as I find then that fewer threads are cut or injured.

In order to frizzle the 4other edge of' the strip I feed it the other end tirst,so that the warpthreads have the same angle to the direction of the feed. When the strip is out at an angle of forty-live degrees with the selvage, the w-arp and weft threads form fringe ot' about the saine length; the strips be cut at a different angle, one set of threads, when frizzled out, project further than the other set. About half an inch or less of projection, is a good width for the fringe.

Both the tool and the apparatus are useful. lVith the tool an operatorvcan frizzle much faster than by picking out the threads with an ordinary needle point, as has heretofore been the practice, and when the tool is combined with the parts of a sewing-machine, as described, a yard of frizzling can be completed at least as quickly as a yard of stitching.

As til'ty or sixty yards of frizzled trimming are often used in a single dress, and the only drawback to its extended use is its enormous expense, it will be per ceived that the invention is of considerable value.

I claim, as of my own invention- 1. The ti-izzling-tool, constructed substantially as herein described.

2. The combination of the reciprocating needlearm, presser-foot, supporting table, and feeding device of a sewing-machine with a ii'izzling-tool,'coustructed substantially as herein set forth..
